Follow general security rules during installation of electric wiring and making connections. Connect the earthing terminal in electric panel to the earthing installation. 02.01.2017 Rev.06 20

General Controls Make sure to perform the following controls before commissioning the burner. Are the electrical connections correct? Is there electricity current? Is there gas? Has the heating system been filled with water? Is the thermostat set at the required temperature? Has the boiler explosion lid been controlled? Is there sufficient air in boiler room (ventilation section cm² = boiler capacity kw x 7) Has the boiler been installed correctly? Has the boiler cover been closed properly? Has the air of the gas line been removed? Has a sealing test been made? Operation of one-stage burner Open the main gas valve, check the gas pressure from the manometer at the valve. (max.300 mbar) Check the boiler thermostat or pressure switch settings. Bring the operating switch on the burner panel to position 1. Burner fan motor will be activated. Ignition will take place at the end of pre-purge process. 3 sec. later, the gas valve will be opened and combustion will occur. Flame control system (ionization) will start flame control. After the boiler water heated up or the boiler pressure has risen, the burner will turn off. Operation of two-stage burner Open the main gas valve, check the gas pressure from the manometer at the valve. (max.300 mbar) Check the boiler thermostat or pressure switch settings. Bring the operating switch on the burner panel to position 2. Burner fan motor will be activated. Ignition will take place at the end of pre-purge process. 3 sec. later, the gas valve will be opened and combustion will occur. Flame control system (ionization) will start flame control. Burner will switch to the second stage (max. capacity) according to the heat requirement. After the boiler water heated up or the boiler pressure has risen, the burner will turn off. Operation of a modulating burner Open the main gas valve; check max 300 mbar gas pressure from the manometer. Open operating switch on the burner panel. Switch on the modulating control switch. Switch automatic-hand switch to automatic. Check the temperature and pressure set values from the modulating control unit. Ignition will take place at the end of pre-purge process. 3 sec. later, the gas valve will be opened and combustion will occur. Flame control system (ionization) will start flame control. In modulating burner, the burner goes into max. capacity according to the signal from the modulating control unit. When the boiler water temperature or steam pressure increase, the modulating control unit will cause burner to run with min. capacity. If the boiler water temperature or steam pressure increases despite the operation of burner with min. capacity, the modulating control unit will stop the burner. 02.01.2017 Rev.06 21

Air Pressure Switch Adjustment While the burner is working without any problem, the air pressure switch is adjusted to desired minimum pressure as follows. Unscrew the screw of the transparent cover and remove the cover. Turn the adjustment wheel in the direction to increase the pressure, note the pressure value at which the burner is failed. Set the pressure switch to a value 1 mbar lower than the pressure value at which the burner failed and close the pressure switch lid. It is recommended that this adjustment is carried out when the burner is at minimum load. Servomotor Adjustment The amount of air is adjusted by means of the servomotor. The servomotor adjustment at two-stage and modulating burners is made by the cams on the servomotor. SQN70 At Two-Stage Burners; I. Red Cam: Adjusts 2nd level max. air. II. Blue Cam: Resets the clamp. III. Orange Cam: Adjusts 1st level min. air. IV. Black Cam: Adjusts 2nd level valve opening degree. At Modulating Burners; I. Red Cam: Performance max. air adjustment. II. Blue Cam: Resets the clamp. III. Orange Cam: Performs min. air adjustment. IV. Black Cam: Not used. Do not open servomotor. Do not interfere with. It may damage servomotor or change burner settings. 02.01.2017 Rev.06 25

Emission Measurement In emission measurements, the following values are accepted as reference according to TS EN 676 +A2 standard. CO < 100 mg/ kwh (93 ppm) %3 O 2 %5 NO x < 170 mg/ kwh Excess air ratio 1,2 λ 1,3 It is important for the boiler to be sealed in order to avoid incorrect measurements during emission measurements. Boiler temperature must be between 40 C and 80 C while making emission measurement in hot water boilers. Capacity Adjustment Exemplary Application: Suppose the required burner capacity is (C) 500 kw. H u = 8250 kcal/m 3 (lower heating value) P = 860 kcal/kw (Value of 1 kw in kcal) Q = C x P Q = 500x860 = 430000 kcal V = Q / H u V = 430000/8250 = 52,12 m 3 /h Set the required gas flow rate over the valve and check this value on the gas counter. Should there be no gas flowmeter in the system, set the burner by using the gas tip lost pressure diagram given at page 15-16. In order to ensure the emission values set the air klappe in each gas flow increase. 02.01.2017 Rev.06 26

Program Relay LME 22 Yellow led on: Indicates that the burner is making pre-purge. Yellow led flashing: Indicates that the burner is igniting. Green led flashing: Indicates poor combustion. Red led on: Indicates burner malfunction. Press and hold the light button for 2 sec. to reset the program relay. Function Controls and Adjustments Operation testing: If the burner switch is turned on and safety circuit is complete (gas pressure switch, thermostat, water level gauge, lower pressure gas pressure switch, upper pressure gas pressure switch, gas leakage control device), turn on the ball valve, burner will start working and turn off the gas valve. Program operation of the relay must be normal until ignition time. During opening of the magnetic valve, gas pressure will drop down and the lower pressure switch will stop the burner for safety. When the ball valve is opened again, gas pressure will increase and lower pressure switch will trip in from safety position and the burner will automatically start operating. Disconnect the ionization circuit or remove the photocell when the burner is operating: Burner will give a fault after burning up. Increase the value of the air pressure thermostat: Burner starts operating, however it should give a fault due to the insufficiency of air pressure. Magnetic valves must not be energized during pre-purge. Check if valves are in closed position! Final Checks Switch of all purges after completion of all necessary measurements. Start and stop the burner at least 3 times to check the operation of the program. Make sure that all safety circuits on the burner and boiler operate properly before leaving the installation site. 02.01.2017 Rev.06 27
